The present invention relates to a liquid treatment system having a sensor comprising a body, the body having a sensing material disposed therein, the sensing material being subject to a change in size in response to a composition of a liquid flowing therethrough; an actuating means disposed within the body and associated with the sensing material; wherein the actuating means is movable between a first position and a second position in response to the change in size of the sensing material to thereby mechanically actuate a switch member, such that when the actuating means is in the first position, flow of an actuating stream of the liquid is allowed by the switch member to thereby hydraulically actuate operation of the liquid treatment system; and when the actuating means is in the second position, flow of the actuating stream of the liquid is prevented by the switch member.

Industrial and residential water treatment systems and devices are disclosed for use in preventing hard water buildup or in removing such buildup. The systems and devices include fixed and removable components for delivering water treatment composition. In addition, novel water treatment compositions and methods of treating water are disclosed.

A water savings system and method for reducing the amount of water needed for adiabatic cooling including the use of a softener and a reverse osmosis device, in which tap water, softened if necessary, is delivered to a reverse osmosis device and softened water alone, reverse osmosis reject water, or softened water combined with reverse osmosis reject water is delivered to spray nozzles for cooling, and reverse osmosis pure water is stored and used periodically to flush the coils to inhibit and/or prevent corrosion from dissolved salts and other solids in the spray water.

An aircraft has: an aircraft fuselage, a cabin region formed in the aircraft fuselage, underfloor region separated from the cabin region by a floor partition, and a fresh-water supply system. The fresh-water supply system has a fresh-water provision unit arranged in the underfloor region. The fresh-water supply system has multiple water extraction units which are each arranged in the cabin region, and a water line network branched off from the fresh-water provision unit and extending to the water extraction units. Each water extraction unit has a shut-off valve, a filter unit and a tapping point, which are coupled in series by means of water lines. Each filter unit has an exchangeable water filter with a first filter material designed for filtering particles out of the water flowing through the water filter and with a second filter material designed for softening the water flowing through the water filter.
